In this report, another group of scenarios for occurrence of earthquake at construction stage, operation stage and closure stage of disposal facility was presented. At first, we compiled information about damage cases of tunnel by earthquake and analyzed conditions for occurrence of damage. Base on this result and the previous report, information of influence of the accidents and human factors on safety functions and information of FEP about THMC variation, we specified events to be considered, which occur by earthquake and influence engineering barriers, natural barriers and long-term safety after closure stage of disposal facility. We compiled influence of the events on safety functions after closure stage of disposal and showed the chains of the influence on long-term safety as scenarios. These results were integrated as a database that could support development of scenarios caused by application of engineering technologies to geological disposal.

Handbook of Generation IV Nuclear Reactors, First Edition, p.283 - 307, 2016/00
Handbook of Generation IV Nuclear Reactors is comprehensive resource on the research and advances in generation IV nuclear reactor concepts and the first edition is issued in 2016. The authors wrote the chapter 11: Generation IV nuclear reactor concepts: Japan, where developments activities on sodium cooled fast reactor in Japan are shown. Especially, concept of Japan sodium-cooled fast reactor (JSFR) is explained on the points of innovative technologies and safety enhancements after the TEPCO Fukushima Daiichi Nuclear Power Plant accident.
